SECTIONAL summon WALL This application is a division of my copendingcase, Serial No. 2,081, filed anuary Y ,13, 1925.; The invention relatesto sectional furnace walls and will be best understood from thefOllOWiIlg. description and the annexed drawings. In these draw1ngs,1nwhich I have shown a selected embodiment of the invention i Fig. lis avertical sectional view through a furnace and boiler, with the furnaceWall constructed according to this embodiment.

a Fig. 2 is a fragmentary vertical view taken from the front of afurnace wall constructed according to this invention. k Figggis a vlewon the line 33 ofFig. 2.

Fig. at is a rear view ofone form of the tile carrying. plates. 7 I Fig.5 is a view on the line 5- 5 of Fig. 4. Fig. 6 is a view correspondingto Fig.4,

but showing: a modified type of plate.

In Fig. 1 I have shown the invention. as

embodied'in a furnace having a combustion chamber ,1, to which fuelissupplied from a.-' burner 2,, here shownas a pulveriaed coal .gburner.The walls ofthe f irnacc extend in V a generally vertical direction, butare inclined f-;outwardly. Above the furnace chamber is .a-boiler 3which may bev ofany suitable type ducts'isfdischarged beneath the floor8 of the furnace, whence it rises through similar ducts in the sidewalls into a duct 9 which dis-f charges itjinto ducts 7 in thefront'wall con-.- nected by suitable apertures 10tothe furnace (chamber.

and fromwhich the hot gases/pass through an outlet flue At aftergivingjup waste heat, to an air'heater 5. Thisheater isprovide'dwith afan 6 by means of which airis forced. th'roughthe' heater and into Wallducts 7.

These ductsare shownas placed inthe rear wall of thefurnace, and thea irfrom these The walls comprise a plurality of vertically extendingI-beams 11 which act as sup-' ports for transversely extendingsupporting. members 12' These members are shown as angle barsboltedtothe flanges of the I-beams,

and having slots 13 permitting relative move.-

spaced, further from the I-beams' than their lower edges, as plainlyshown in Fig. 3.

The arrangement is preferably such that each plate 16 will rest upon onesupporting memher and leans, or outwardly'against the next higheriemberwhich thus prevents its outward movement.

Each plate 16 preferably supports a plurality of tile 17', the uppermosttile oneach plate overlapping thet'op edge of the plate andcontactingwith the tile supported on the next higher plate, asplainly shown inFig. 3. The tile may' befof thelform shown at 17 in Fig. .3, or theymaybe inthe form sh'ow n at 18 and 19 in the same figure. The tile17 areplain fiat tile with the top one notched,

as shown at 20,' to' overlap the topedge ofthe "plate 16. ,QThf tile 18andfl9, onthe other hand, arespecial tile'andit will be seeiithat theyare much thicker. Thetile 18 is recessed,

asshown at 21, so as to receive the next lower tile, and, the-t le 19has a recess 22 in which is received the bent out upper edge of the"plate x 16. f This dorms interlocking means'between the plate andthetile, and it will be seenthat by this arrangement the plates areadequately protected the tile from the; heatof the furnaceiindi atthesame tiin e,'the t;ile are -i' .li'eferrlng toFigs. 4L and 5, itwillbelseen that-each of the plates 16 is providedwith outwardly extendingribs 23, which extend into the ducts 7 back of the inner wall. These"ducts are formed between I -beams '11 and the ,space left betweentherear or outward flanges .Z JQOf thfeI-beams and a, casing 25.
